How to make a moving enemy shoot at the player rather than the player's spawn?

Hi. I am making a top-down shooter and I was having an issue with getting a moving enemy to shoot at the player. The enemy in question shoots at the player's initial spawn but not at the player's current location. Below is the script that controls all enemies and enemies shooting. I could use some help.

 using UnityEngine;
 using System.Collections;

 public class Enemy : MonoBehaviour
 {
     public float speed;
     public string shipType;
     public float travelTime;
     public float restTime;
     public GameObject spawner;
     public GameObject bullet;
     public GameObject player;
     
     public bool canShoot;
     public bool lookAtPlayer;

     void Start()
     {
         float posX = transform.position.x + offsetRange * Random.value;
         Vector2 offset = new Vector2(posX, transform.position.y);
         transform.position = offset;
     }

     void Update()
     {
         ShipControl(shipType);
     }

     void ShipControl(string type)
     {
         switch(type)
         {
             case "basic": Move(); break;
             case "shooting": Move(); break;
             case "moveShoot": Move(); PointAt(); break;
         }
     }

     void Move()
     {
         if(travelTime > 0)
         {
             transform.Translate(Vector2.down * speed * Time.deltaTime);
             travelTime -= 1 * Time.deltaTime;
         }
         else if(restTime > 0)
         {
             if(canShoot)
                 Shoot();
             restTime -= 1 * Time.deltaTime;
         }
         else
         {
             if (canShoot)
                 Shoot();
             travelTime += 1;
             Move();
         }
     }

     void PointAt()
     {
         if(spawner != null && player != null)
             spawner.transform.up = player.transform.position - transform.position;
     }

     void Shoot()
     {
         if(bullet != null && spawner != null)
         {
             GameObject thisBullet = Instantiate(bullet, spawner.transform.position, spawner.transform.rotation) as GameObject;
             canShoot = false;
         }
             
     }
 }
